From dccc7228b5de7658f79ad0074a57a8798462c533 Mon Sep 17 00:00:00 2001 From: Manasi Navare Date: Mon, 21 May 2018 17:25:41 -0700 Subject: [PATCH] drm/i915/icl: Add DDI HDMI level selection for ICL This patch adds a proper HDMI DDI entry level for vswing programming sequences on ICL. Spec doesn't specify any default for HDMI tables, so let's pick the last entry as the default for now to stay consistent with older platform like CNL.
